Figure 2: Yukgunja-tang water extract reduced the numbers of inflammatory cells in BALF samples of cigarette smoke/lipopolysaccharide-exposed mice. (a) Schematic diagram of the experimental protocol. On 5 days/week, mice were administered with vehicle, roflumilast, or Yukgunja-tang water extract for 2 h and then exposed to cigarette smoke of eight cigarettes. Mice were treated with lipopolysaccharide twice on days 8 and 23. (b) The image of macrophages (arrow), neutrophils (arrowhead), and eosinophils (asterisk; magnification, ×400). (c) Differential cell counts in the NC, cigarette smoke/lipopolysaccharide, roflumilast, and Yukgunja-tang water extract groups. Values are presented as the mean ± standard error of the mean (n = 6). # P < 0.05, compared with the NC group
